1.1. Depending on Commons Lang

1.1.1. Problem

You want to use Commons Lang because your program needs to use some of the simple utilities this component provides, such as array manipulation, date manipulation, and enums.

1.1.2. Solution

To use Commons Lang in a Maven 2 project, add the following dependency to your project's pom.xml:

Example 1.1. Adding a Dependency on Commons Lang

<dependency>
      <groupId>commons-lang</groupId>
      <artifactId>commons-lang</artifactId>
      <version>2.4</version>
    </dependency>

1.1.3. Discussion

If you are not sure what this means, I'd suggest reading Maven: The Definitive Guide. When you depend on a library in Maven 2, all you need to do is add the dependency groupId, artifactId, and version to your project's dependencies. Once you do this, Maven 2 will download the dependency and make it available on your project's classpath.
